Hello @diego

However, from a system design perspective, I was wondering if it would be better to:
keep the system disk small (OS + Cloudron core)
attach a separate disk dedicated to mail storage
Yes you can do that.
I also do that with my private Hetzner server so I can scale up the CPU/RAM and have the storage seperate.
@diego said:
Will the Cloudron backup system still include it normally?
Yes.
If you move e.g.: /home/yellowtent/boxdata/mail to /mnt/sdd1 and create a symlink so /home/yellowtent/boxdata/mail => /mnt/sdd1 this still works.
What you can always to is creating a small Cloudron server to test and tinker as much as you like.
This way you get a better feeling for everything without risking any damage to production.
